Integrated Circuit Systems, Inc.
Frequency Generator for Digital Video Systems he
General Description
The ICS9118-01 and ICS9118-02 are low-cost, highperform-ance clock generators designed to support digital video sys-tems. 27 MHz VIDEO, 1.8 MHz UART and AUDIO clocks are generated from the recovered 27 MHz signal. The on-chip crystal oscillator can be used in conjunction with an exter-nal D/A conversation circuit to provide ±130 ppm clock recovery using a standard 27 MHz crystal (contact ICS for application details).
